Letters Patent No. 106,797, dated August 30,1870.

IMPROVEMENT IN ROLLE-TEMPLES FOR LOOMS.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these presents may come Be it known that I, Wannen W. DUTGHER, of Hopedale, ofthe county of Worcester aml State of Massachusetts, have invented a new and useful Improvement 'in Roller-Temples for Looms for Weaving Cloth; and do hereby declare ,the same to he fully described in the following specification, and represented in the drawing, of which- Figure 1 is a top view, and

Figure 2, a. front elevation of one of my improved loom-temples.

Figure 3 is a v erticui section taken in line of the axis of the compound ordilierential roller.

Figure 4 is a top view of the trough.

Figure 5 is a top view of t-he compound or differential roller.

Figure (i is au under-side view of the roller-cover.

In weaving broadcloth, or other fabrics leaving alist at either 0r each edge, it is customary to employ n much coarser wi-ol or material for the list thanV for the body of the cloth. Owing to the fact that in the process of pulling the clot-h after it is woven the list will, or generally does, shrinkvery much more than the body part of the cloth, it becomes necessary to weave the list longer than the body, whereb)1 the list', after heilig woven, has a corrugated or rufed appeal'- a'nce, all of which becomes removed by the process of felling the cloth.

Previous to my invent-ion it has beenfouud very difficult to produce a temple which would answerwell for use in a loom for making a listed cloth. I have, however, succeeded in accomplishing such result.

In carrying out my invention I' make that part of the temple-roller which is to operate on the listcylindrical, and of a diameter greater than the cylindrical part which is to operate on the body of the cloth, and 1 also form the temple-trongl1,and the cap thereof, larger in diameter about the list-part of the roller than they are about the body-portion, each part of the trough being. preserved at a like distance, or about so, from the part of the 4roller encompassed by it.

In the drawing the temple-roller A-is represented as composed of two cylindrical portions, a c, united by an intervening conic or tapering frnstum, b, the part a being of greater diameter than the vpart c, which is to operate on the body part of the cloth, while the part a may be in operation on the list.

Each part a c is to be studded with teeth, t, like an ordinary temple-roller.

The duplex or differential roller thus made is mounted on a spindle, B, supported in and by the cap tanees from it as -to admit the list and body of the cloth to properly pass through the trough and against the-roller, in order that the teeth ofthe latter may lsuitablyact on the cloth. The interiorl of the cap, .y

where encompassingthe roller, is to be concentric with it, and generally at the saine distance from it throughout. l

From the above it will be seen that.' while the temple may be in use, the part a of the roller will revolve with the part c, and will take up the list faster than the part o does the body of the cloth; The diameters,

as well. as the circumterences of the parts c and c,

should be in proportion to the length of list to any given length of body of the cloth.

The temple-roller spindle, instead of being supported by the cap, may be sustained by the trough, as in various other roller-temples,4 but l prefer to apply the spindle directly to the cap, as, when so applied, it may' be supported ator near each of the ends of vthe spindle, whereas, when supported by the trough, the support has to'be at one end only then-of.

l would also remark thatthe differential roller, as made with its parts a` c connected by a couic or 'tapering frustum, b, is much preferable to a diiereutial roller composed` only of two cylinders of ditierent diameters, with the end of one abutted against; and Connected to that of the other, as suoli a roller, though useful, cannot he employed to the advantage of one having its cylinders connected byfa tapering trustum.

I claiml. The temple-roller, as made of the connected list and bodycyliuder c c, havingr ,different diameters, as and for the purpose as described.

2. In 'combination with the di`erential roller A, formed of the connected list and body-cylinders a c of different diameters, as described, the trough, as made with its list and body-receiving parts of diiier'ent diameters, and arranged with the parts c c of the roller, as explained.

3. ln combination with the d ilierential temple-rol ler and trough, substantially as described, the cap, as formed, with its parts embracing the list part cof the roller of a greater diameter than the part covering the body part c of such roller, the whole being as set forth.

4. The temple-roller, as made with the part-s c c of different diameters, and connected by a conic frustuin -b, the trough and cap to operate with such roller, bep ing substantially as described and represented.
